Calculate the yearly feed requirements of working animals by species

Description

Calculate the yearly feed requirements of working animals by species and region. This function uses user-supplied data supplied via amw_analysis_data_path for daily feed requirements of working animals on working and non-working days by species and region, and user-supplied data for the number of working days by species and region to estimate the total yearly feed requirements.

Usage

calc_yearly_feed(
  .df,
  amw_analysis_data_path = MWTools::amw_analysis_data_path(),
  concordance_species = MWTools::conc_cols$species,
  method_source = MWTools::mw_constants$method_source,
  wa_feed_sheet = MWTools::amw_analysis_constants$wa_feed_sheet,
  wa_days_hours_sheet = MWTools::amw_analysis_constants$wa_days_hours_sheet,
  working_days_col = MWTools::amw_analysis_constants$working_days_col,
  nonworking_days_col = MWTools::amw_analysis_constants$nonworking_days_col,
  working_hours_col = MWTools::amw_analysis_constants$working_hours_col,
  working_day_feed_col = MWTools::amw_analysis_constants$working_day_feed_col,
  nonworking_day_feed_col = MWTools::amw_analysis_constants$nonworking_day_feed_col,
  working_yearly_feed_col = MWTools::amw_analysis_constants$working_yearly_feed_col,
  nonwkg_yearly_feed_col = MWTools::amw_analysis_constants$nonwkg_yearly_feed_col,
  total_yearly_feed_col = MWTools::amw_analysis_constants$total_yearly_feed_col,
  amw_region_code_col = MWTools::conc_cols$amw_region_code_col
)

Arguments

.df	A data frame containing tidied data for the number of live and working animals. Usually produced by calling the tidy_fao_live_animals, add_concordance_codes, trim_fao_data, get_working_species, calc_working_animals, and calc_sector_split functions in sequence on the raw FAO data.
amw_analysis_data_path	The path to the animal muscle work analysis data, containing feed requirements of working animals in agriculture and transport, by species, country, and over time. Set to the function MWTools::amw_analysis_data_path(), by default, which returns the path the analysis data bundled with the MWTools package.
concordance_species	See MWTools::conc_cols.
method_source	See MWTools::mw_constants.
wa_feed_sheet, wa_days_hours_sheet, working_days_col, nonworking_days_col, working_hours_col, working_day_feed_col, nonworking_day_feed_col, working_yearly_feed_col, nonwkg_yearly_feed_col, total_yearly_feed_col	See MWTools::amw_analysis_constants.
amw_region_code_col	See MWTools::conc_cols.
